Patented Oct. 7, 1930 UNITED STATES PATENT OFFICE ARTHUR T. BATE MAN ANDFRANK E. STOREY, OF DETROIT, MICHIGAN, ASSIGNOBS TO IBOHN ALUMINUM &BRASS CORPORATION, 013 DETROIT, MICHIGAN, A CORPORA- TION OF MICHIGAN IMOLD STAND Application filed-August 27, 1928 Serial No. 302,284.

The invention relates to stands for supporting molds and has for one ofits objects the mounting of a mold so that it may tilt during thecasting operation and thereby pro- 5 vide for the escape of air from themold cavity and the filling of the mold cavity with the molten metal.Another object is to so mount the mold that it may be continuouslytilted during the pouring operation. Further 10 objects of the inventionreside in the novel features of construction and combinations andarrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 is a front elevation of a mold stand embodyingour invention;

Figure 2 is an end elevation thereof.

For the purpose of providing for the escape of air from the mold cavityof a mold so that this mold cavity may be completely filled with moltenmetal, we have provided a construction of mold stand by means of whichthe mold may be tilted during the casting operation. As shown, 1 is thebase of the members 2 at its ends, each of which has formed in its topthe transversely extending V-shaped groove 3, the grooves of the twoframe members being in alignment. 4 1s aannular passage 10 whichencircles the mold cavity and is connected therewith bysuitablerestricted passages 11. Furthermore, the mold has the ventpassages 12 leading upwardly from the annular passage 10 to thetop ofthe mold. The arrangement of mold is such that air within the moldcavity may escape through the restricted passages 11,

the annular passage 10 and the vent pasmold stand having the triangularframe pivotal member or platform upon which is fixedly secured the base5 of the mold 6.

foractuating said movable member to For the purpose of swinging thepivotal member 4 upon the base 1 to thereby tilt the .mold so that theair in the mold cavity will not be trapped and can completely escape, wehave provided the lever 13 pivotally connected to the base 1 near itsbottom so that this lever may be actuated by the operators foot. 14L isa rod pivotally connected at one endvrto thelever 13 and at the otherend to the pivotal member 4 laterally beyond the gudgeons 7. To normallyhold the pivotal member 4 in a predetermined position relative torthebase 1 and in the present instance in a horizontal position, we haveprovided the coil spring 15, one end of which is'connected to thepivotal member 4: on the side of the gudgeons 7 opposite to the pivotalconnection of the rod-14 to the pivotal member 4:. -The other end ofthis coil spring is secured to the base 1 near its bottom. 17 and 18 arebrackets secured to'the base 1 near its topand on opposite sides ofthegudgeons 7 for re spectively limiting the swinging move- .ment of thepivotal member 1 under the influence ofothe coil spring 15 and theinfluence of the lever 13 and the rod 14;. I

l Vith this arrangementof molding stand, the operator may during thepouring of molten metal through the gate 9 into the mold cavity 8gradually and continuously swing the pivotal member 4 to thereby tiltthe mold by applying foot pressure upon the lever 13. As a result, airwithin the mold cavity may be completely displaced by the molten metaland escape through the restricted passages 11, the annular passage 10and the vent passages 12.

What we claim as our invention is:

1. In a stand for supportinga mold, the

combination of a base, mold supporting means upon' said base, includinga member movable to provide for tilting of the mold, and means providefor continuous and gradual tilting of the mold during the pouringoperation.

2. In a stand for supporting a mold, the combination of a base, moldsupporting means upon said base, including a member movable toprovidefor tilting of the mold, a pivotal lever uponsaid base, and meansconnected to said lever and movable member for actuating the latter fromthe former.

3. In a stand for supporting a mold, the combination of a base, a moldsupporting pivotal member upon said base, a pivotal lever upon saidbase, agd means between said pivotal member an lever for actuating theformer from the latter.

n a stan fe urro i a m l he qenbiaati n f a a m d upp r i memberpivotally mounted upon said base, means between said pivotal member andbase for resiliently holding said pivotal member in a predeterminedposition relative to said base,a pivotal lever upon said base, and meansbetween said ivotal member and lever for swin ng the ormer from thelatter.

6. n a stand for supporting a mold, the combination of a base, a moldsupporting member mounted for tilting movement on said base, ieldablemeans for normally maintaining sa d member in a predetermined positionand resisting movement thereof,' and means for tiltin said memberagainst the resistance of said %rst named means during the pouringoperation.

" 0. Int. stand for supporting a mold, the combination of a. base, amold supporting member mounted for tilting movement on said base meansfor normally maintainin said member in a predetermined osition anresisting movement thereof, an means for tiiting said member againstcombination oi a member mounted said base, resilient base, "a moldsupporting for tilting movement on means for normally maintaining saidmember in a predetermined position and resisting movement thereof, andmeans for tiltin 4 said member against the resistance of sai first namedmeans.

8. In a stand for supporting a mold, the combination of a base, a moldsupporting member mounted for tilting movement on member against theresistance of sa d first named means during the pouring operation. 10.In a stand for supporting a mold, the

combination of a base, a mold supporting member pivoted intermediate itsends upon id base, a spring at one side of said PIVOt r resistingmovement of said supporting the resistance of said first named means,including a foot I operated lever pivoted on said base.

7'. In a stand for supporting a mold, the

member, and means at the opposite side of said pivot including a leverpivoted to said base for moving said supporting member against thetension of said spring.

11. In a stand for supporting a mold, the combination of a base, atiltable mold supporting member upon said base, and means providing forthe gradual and continuous tiltinglof the mold during the pouringoperation inquding an actuator for said mold supporting member. y

12... In a stand for supportin a mold, the combination of a base, atiltalie mold sup- PQIQ member upon said base, means for norma ymaintaining said member in a pre determined position and resistingmovement thereon and manually operable means for tiltin said memberagainst the resistance of said rst mentioned means.

In testimony whereof we aflix our s1gna-' tures,
